Hi Ted,
It is a Monarc, made in Albury, it has ended up half under water twice, and it sat on the back of my truck for years out in the open. Not sure how many amps it runs, I have always run it full amps with 12 gauge rods and half with 14 gauge. Cost me 52 pounds when I bought it which was a few weeks wages at the time. Once I carried it up 3 flights of stairs, these days I can pick it up but I can't walk with it
